Junction box routines called at the beginning or end of timesteps or coefficient loops are expected to be mainly used for custom solution monitoring, program steering or coupling with other applications. A good example application is the coupling of CFX with a structure analysis code to calculate the fluid-structure interaction.

The Abort option for Junction Box Location is a special call that occurs just before the CFX-Solver terminates abnormally (for example, if an MMS error occurs). It is designed to enable you to shut down programs that might be running in conjunction with the CFX-Solver or other system level operations required as the CFX-Solver process ends. The CFX-Solver exit status is provided in the common block /CFXSTATUS/ STATUS. STATUS is an integer.
